Love Boards of Canada, a truly beautiful ambient electronic experience. Appreciate Aphex Twin but have never really been able to jive into it. Just recently heard Com Truise and like what I hear so far. All of the others I will have to check out for sure.
Some of my recent favorites that you might enjoy
Emancipator - This guy is in his low 20's. Solid brilliant electronic composer

Sigur Ros - Out of Iceland. Words will never be adequate to describe a power of this magnitude, Sigur Ros are ghods on earth.

Have fun. Be safe!
“We do not grow absolutely, chronologically. We grow sometimes in one dimension, and not in another; unevenly. We grow partially. We are relative. We are mature in one realm, childish in another. The past, present, and future mingle and pull us backward, forward, or fix us in the present. We are made up of layers, cells, constellations.”
